"You have been disconnected. (BLZ51903006)"

Again with this error, i cant connect and no one online on friendlist. Anyone with this problem today?

OBS: After 1 hour i conected normaly on the game.

What ISP are you using? I’m having a problem with Comcast in all Blizzard games where I will get disconnected. I’m able to immediately log back in but it will eventually disconnect again. The strange thing is it’s just Blizzard there are no connection issues or dropped packets to anything else.
